Texture displacement looks different in viewport and render

Using a principled shader, I'm using a texture file for the displacement. With effect scale set to 1, I have the expected result at render time, but in the viewport window the effect scale is too big.

 

The textures used are:

Is the Principled shader's Effect Scale tagged with 'ogl_displacescale' (in Edit Parameter Interface). If it's not, it'd be using a displacement scale of 1.
